Reference of 17325-26-7, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 17325-26-7, name is Methyl 1H-imidazole-5-carboxylate belongs to imidazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below.
To a stirred solution of (S)-2-((4-iodopyridin-2-yl)amino)butan-1-ol (0.8 g, 1.71 mmol), in DMF (5 mL) was added potassium phosphate (0.32 g, 2.57 mmol), methyl 1H-imidazole-4-carboxylate (0.323 g, 2.57 mmol), and L-proline (0.039 g, 0.34 mmol). The mixture was degassed with argon gas for 20 min, then copper(I) iodide (0.065 g, 0.34 mmol) was added, and then the mixture was stirred for 12 h at 150 C. in a sealed glass tube. Then the reaction mixture was cooled and quenched with water (35 mL), and extracted with ethyl acetate (3×60 mL). The combined organic layers were dried over sodium sulfate, filtered and concentrated under reduced pressure, and the residue was purified by gradient column chromatography eluting with 80% ethyl acetate in n-hexane to give (S)-methyl 1-(2-((1-hydroxybutan-2-yl)amino)pyridin-4-yl)-1H-imidazole-4-carboxylate as an off-white semi-solid, (0.25 g, 32% yield). 1HNMR (400 MHz, DMSO-d6): delta 8.42 (s, 1H), 8.38 (s, 1H), 8.02 (d, J=6 Hz, 1H,), 7.67 (m, 1H), 6.85 (m, 1H), 6.75 (s, 1H), 6.36 (d, J=8.4 Hz, 1H), 5.72 (s, 1H), 4.61 (s, 1H), 4.12 (m, 1H), 3.81 (d, J=4 Hz, 1H), 3.78 (s, 3H), 3.46 (t, J=5.6 Hz, 1H), 3.34 (t, J=5.6 Hz, 2H), 1.60-1.44 (m, 1H), 1.33-1.24 (m, 1H), 0.89-0.83 (m, 3H). LC-MS calcd exact mass 290.14, found m/z 291.2 [M+H]+.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, Methyl 1H-imidazole-5-carboxylate, other downstream synthetic routes, hurry up and to see.
